Neighbor gave me a free generator that didn't run. Turns out it had water in the gas. I plugged a trouble light into it and it was very dim . This is a brushless generator, do they also need to be "excited/repolarized" and how do you do it?. I have never had a generator before. Or is it shot?

Check for a manual in our Manuals Section. I've had a bunch of the powermates but they all had brushes. They were from the end of the generator. When they had trouble, I would pull the brushes and clean them. I would then use Q tips soaked in carb cleanner to clean the commutator. If you are getting some juice out of it, I don't think exciting will help. Post some pics. Good Luck, Rick

Brushless = alternator, it creates an AC output. No brushes required.
